Comment #2 on issue 1614 by fredrik.johansson: Real tuple argument weirdness http://code.google.com/p/sympy/issues/detail?id=1614
The string conversion calls mpf_neg and prepends a "-" if the sign is nonzero. mpf_neg assumes the sign to be either 0 or 1, so flipping it returns a nonzero sign if it's something else. The bc is used to determine the size of the number. This in turn is used to determine how many bits or digits to pad with or throw away when converting from binary to decimal. It's not surprising if setting a wrong value gives strange output. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
